GULTIVATOR.

Specification of Letters Patent.

Patented May 31, 1910.

Application led July 10, 1909. Serial No. 506,989.

To all whom it may concern:

Be it known that I, PAUL T. ZoLLARs, a citizen of the United States, residing at Edgerton, in the county of Platte and State of Missouri, have invented certain new and useful Improvements inV Cult-ivators, of which the following is a specification.

My invention relates to improvements in cultivators.

The object of my invention is to provide, in a cultivator of the sled type, carrying wheels which are movable to and from positions in which they will carry the sled. So far as I am aware, sled cultivators have not heretofore been provided with carrying wheels so adjustable. With sled cultivators not having carrying wheels the cultivators can only be used advantageously during the vlirst cultivation of the listed grain, afterward the furrows are not suticiently prominent to guide the runners of the sled and another form of cultivator must subsequently be used. By providing a sled cultivator with wheels adjustable to and from a position in which they will carry the sled, no other cultivator is required to be used subsequent to the lirst cultivation.

Another novel feature of my invention consists in the novel mechanism by which the cultivating devices may be adjusted rotatively around axes disposed at right angles to each other, thereby enabling the operator to dispose the cultivating devices in any desired position.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate my invention, Figure 1 is a plan view. Fig. 2 is a side elevation. Fig. 3 is a vertical section, enlarged, on the dotted line a-b of Fig. 1. Fig. 4 is a cross section on the dotted line c-fl of Fig. 1. Fig. 5 is a plan view of a portion of one of the cultivator bars, enlarged. Fig. 6 is an enlarged cross section on the dotted line c-f of Fig. 1.

Similar characters of reference denote similar parts.

1 denotes the top of an ordinary cultivator sled, having the usual longitudinal runners 2.

3 and 4 denote respectively two inverted U-shaped bars having horizontal arms 5, secured to the top 1. On the upper end of the bar 4 is a seat 6. Vertically adjustable respectively in holes provided in the arms 5, are vertical studs 6, the lower ends of which extend horizontally outward and have respectively mounted thereon rotary carrying wheels 7, which are preferably provided with peripheral flanges 8 to prevent lateral slipping of the wheels. Secured respectively by set screws 9, on the studs 6, are collars 10, upon which respectively rest the ends of the arms 5. By loosening the set screws 9, the studs 6 may be vertically adjusted to and from a position in which the carrying wheels 7 instead of the runners carry the cultivator.

Rotatively mounted in bearings 11, secured to the rear end of the sled, is a rock shaft 12, having a crank 13 which is connected to the rear end of a horizontal rod 14, the forward end of which is pivoted to a vertical lever 15, the lower end of which is pivoted on a horizontal bolt 16, supported iu two bearings 17, secured to the top 1. By swinging the lever 15 forward and backward, the operator can rock the shaft 12 so as to swing upward and downward the cultivating devices carried by said shaft. The lever 15 may be locked in the position to which it may be adjusted by a bolt 18, slidably mounted longitudinally in projections 19, provided on the lever 15, said bolt being adapted to enter notches 20, provided on the curved upper side of a plate 21, the bifurcated forward end of which is secured to opposite sides of the U-shaped plate 3. A coil spring 22, encircling the bolt 18, and bearing at its upper end against the upper projection 19, and at its lower end against a pin 28, in the bolt 18, normally forces said bolt into the notches 20. Pivotally mounted on the lever 15, above the bolt 18, and connected therewith by a rod 26, is a bell crank lever 25, by swinging which the operator withdraws the bolt 18 from the notches 20.

27 denote the cultivating devices comprising preferably ordinary rotary cultivating a set screw 29. Rotatively mounted on the rear end of the arm 28, is a horizontal member 30, the forward end of which fis vprovided with two holes adapted to receive two rearwardly extending projections 31, of a locking member 32, which is rotatively mounted on the arm 28, forward of a circular plate 33, provided with a .centr-.al hole through which extends the arm 28, to which the ,plate 33 is secured .by :a hoy ..34- The plate 3.3 is provided with a plurality7 of holes 13,5, adapted to receive therethrough the proieotions 3l. A coil :spring 3G encroles the .arm 2,8 and has its rear end bearing against .the forward side of the locking member 32, .the iorward .end .of the spring .bearing against the enlarged forward ,end of the Varm 218 By .compressing the spring 3,5 and with,- `drawing the projections 3.1, from the plate 33, the member 30 and locking member 32 may be rotated on the arm 258 to positions desired, after which the projections 3l are inserted in .the two openings 35, which register with the openings provided in the *cir/e cular forward end of the member 30. The rear end of the member 3,0 is biiurcated and its two arms 37 disposed one above the otherbar 3,8, .on which the cultvator `disks 27 are rotatively mounted. A vertical bolt :39 en tends vertically through holes provided therefor in the arms 37 .and bar 38, The bar 38 is provided with a plurality .of holes 40, disposed ooncentrieallyV with the bolt 39 and adapted to receive therethrough the ver.- tical `rarms of an inverted Ufshaped locking member 4l, the horizontal portion of which is provided with a central .hole through which extends the bolt 39. The vertical arms of the locking member` 4l also extend through two holes provided in each of the arms 37. A coil spring 4.2, encircles the bolt 39 and has its upper end bearing against the head of the boltand its lower' .end against the looking member ril,- By lcompressing the springV 42 the Vertical arms of the lock.- Hg member 41 may be withdrawn from the bar 38, thereby permitting said bar .to be swung horizontally to the position'desired, after which the lspring 4-2 is allowed to force the locking member 4l into the open: ings 4,0, which at that time are in alinement with the holes in the arms 3,7.

F rom the above it will bo understood that .the bar 38 may .be swung horizontally so .as to dispose theioultivating disks more or less parallel with the turrows and the members 30 may loe rotatively adjusted so as to swing the bars 38 to positions at greater o r less angles to the horizontal.

In Cultivating vthe* drilled grain the first time, the set screws 9 are loosened and the studs o are moved upward to a position in which the runners 20 will support the sled.. Subsequent to the first cultivation, the studs Between the arms 37 is 1a transverse 6 are moved downward and secured by the set screws 9 in ositions in which the carrying wheels 7 will support the sled.

Various modifications of my invention, within the scope of the appended claims, may be made without departing from its spirit.

Having thus .described my invention, what I claim and desire to secure by Letters Patent, is

l. In .a icultivfator, the .combinati-on with a rock shaft., of .arm .secured radially .thereto, .a member :secured rotativcly on the arm and having `a hole, a plate Asecmrecl rigidly to the arm :and having a plurality of holes concentric with the arm, ,a locking device rotative on .the arm and mov-able lengthwise thereon into and out of the holes in .the plate and said member, spring for normally forcing the locking .device into said holes., and `means for supper-.ting .cultivating devices .on said member.
